▎ 摘　　要

PVA-BB/GO-Fe3+/agar hydrogels (BB is configured by 1:1 configuration of 0.04 mol L-1 boric acid solution and 0.04 mol L-1 borax solution) are designed with excellent mechanical and electrical properties due to their triple cross-linked network, and they maintain stable performance in various tests, which is sufficient to support the use of hydrogels in multiple scenarios. Meanwhile, the tension responsiveness of the PVA-BB/GO-Fe3+/agar hydrogel allows it to rapidly transmit signal changes upon tension changes. Finally, maintaining increased energy dissipation and strength enhancement during the loading-unloading cycle provides the possibility of long, stable operation. In summary, it is believed that PVA-BB/GO-Fe3+/agar hydrogel has significant potential in the field of flexible sensors and is expected to be fabricated as a sensor for motion monitoring.
